Abstract (en)
In general, according to one embodiment, there is provided a nonaqueous electrolyte battery. The nonaqueous electrolyte battery includes a positive electrode containing a lithium nickel cobalt manganese composite oxide, and a negative electrode containing a spinel-type lithium titanium composite oxide, and a nonaqueous electrolyte. The nonaqueous electrolyte battery shows improved capacity after an aging step because the capacity difference between the positive and the negative electrode is reduced.
